ASSEMBLY STEP 1
For Sliding and Swinging Gates ONLY
Assemble the Rail and
Attach the Chain Pulley Bracket
To avoid installation difficulties, do not run the
garage door opener until instructed to do so.
1. Place the 3 rail sections on a flat surface for
assembly. The end sections are identical. Make
sure the "arrow label" on the center section is
pointing in the direction shown in the illustration.
2. Connect the center section and the 1/4" lock nuts
to the end sections from the same side, as
shown.
NOTE: If rail is not assembled exactly as shown,
trolley will not travel smoothly along length of rail
or it will hit against nuts.
3. Insert the carriage bolts from the opposite side of the end
sections. Tighten the nuts. When assembled, rail has a front-to-
back position as shown.
4. Position the chain pulley bracket on the front end of the rail as
shown. Fasten securely with the hardware provided.
NOTE: When tightening the bolts be sure to keep bracket
parallel to the rail. Otherwise, the rail may bow when the
opener is operated.
